lession 4: Fund me, withdraw is not working as expected.

[Gukirt007]

hey, is your withdraw function working?
i amount from contract is gone but did not received in my wallet?

contract address: 0xC21ad10b629Fd0f149941342A0563853c3B1867e

https://goerli.etherscan.io/address/0xc21ad10b629fd0f149941342a0563853c3b1867e

please do let me know if amount is reflected back to your wallet.

In the contract transactions there's a withdraw function call, but it has withdrawn 0 eth...maybe in your contract you're just setting the amount for the address to 0 and not using this value to send to the owner?

[Gukirt007]

this is how my withdraw function looks like

function withdraw() public onlyOwner {
    for (uint256 i = 0; i < funders.length; i++) {
        address funder = funders[i];
        totalFunded[funder] = 0;
    }

    //reset funnders array
    funders = new address[](0);

    //tranfer
    // payable(msg.sender).transfer(address(this).balance);
    // owner.transfer(address(this).balance);
    //send
    // bool sendSuccess =  payable(msg.sender).send(address(this).balance);
    // require(sendSuccess, "Sending failed!!");

    //call
    // (bool sendSuccess, ) = payable(msg.sender).call{
    //     value: address(this).balance
    // }("");
    // require(sendSuccess, "Sending failed!!");
}

It can be a silly question, but you just copy and pasted your code here? If YES, then all I can say to you is that the code after the line funders = new address[](0) is all commented, you need to take the // from the lines where you were supposed to send the ETH to the owner

[Gukirt007]

oh the silly me , actually i was trying to use all three options,

with transfer:
payable(msg.sender).transfer(address(this).balance);

with send:
bool sendSuccess = payable(msg.sender).send(address(this).balance);
require(sendSuccess, "Sending failed!!");

with call
(bool sendSuccess, ) = payable(msg.sender).call{ value: address(this).balance}("");
require(sendSuccess, "Sending failed!!");

i have used all above methods ( and yes i make them commented in same code so i could get idea what i have already tried ).
the above methods can be found on https://solidity-by-example.org/sending-ether/

however bellow peace of code is suggested by chatGPT:
owner.transfer(address(this).balance);

AND NONE OF THEM WORKING

well, I don't want to doubt you but I just finished this lesson and tested mine and it worked.

From what I see from your piece of contract comparing to mine, they're the same.

I also looked into the transaction that you've attached and I saw the withdraw call in there and indeed has the eth amount being withdrawn in there, to your wallet.

I don't know how I can help you from here, maybe the funds came back to you but you didn't notice? Did you tried sending a big amount so that if you withdraw, you see it clearly coming back?

I hope you can find out what are we missing

I don't know if you said didn't withdraw because you saw in the transaction list from the contract that the column with the name Value was with 0, but if you look inside the transaction theres a section in the To: that has the information about the value withdrawn.
